(Continuation from yesterday)

"Absolute safe control system does not exist absolutely."

I know it well.

Control systems kill human being.

They must kill us.

Airplane and trains are growing up, killing people.

Only "atomic energy" cannot be an exception.

----

I am a person who is on the side of control system, and I am hammered in fierce sense of values for "security" and "human life" thoroughly.

For example,

I have been rejected some "new system" that I had proposed in my company.

"Ebata. if you want to insist that the new system which you suggest are absolutely safe, prove and demonstrate it logically and mathematically"

It is said in my field "control system"

"Probatio diabolica"

The new system exists in my mind (or in the patent application), so there is no way to prove and demonstrate "the absolute safety with the existing system.

But this is a common sense in my field, and I have to continue working in the common sense.

For example,

The system is going to stop anything, even if the commutation messages are cut off for 1/100 second only.

It is not a story of "nuclear plant systems".

It is the story of "the vehicle" which we use for commuting and attending school routinely.

In spite of the design effort of control systems, our expectation is always betrayed and control systems continue killing people anywhere in the world.

About my hypnosis of "absolute safe control system does not exist absolutely."

Only one counterexample is enough for me.

"There is a year that no railway accident, no plane accident, and no plant accident happen in year-end news"
